Scope: This document specifies the principle and process, technical requirements, tests, operation system and energy-saving evaluation of high-temperature top-fired hot blast furnaces for blast furnaces. This document is applicable to the design, installation and commissioning of high-temperature top-fired hot blast furnaces (referred to as top-fired hot blast furnaces) for new construction, expansion or renovation of iron-making blast furnaces in steel enterprises.

Introduction

1. Background of Standard Formulation and Technical Evolution

GB/T 30163-2023 "Technical Specification for Energy Saving of High-Temperature Top-Fired Hot Blast Furnaces for Blast Furnaces" is a comprehensive revision of the original standard GB/T 30163-2013. This revision optimizes and upgrades the terminology, technical requirements and test methods on the basis of retaining the core framework to meet the development needs of modern blast furnace ironmaking technology. The new standard introduces more energy-saving technical requirements and strengthens environmental protection indicators, reflecting the industry's technological evolution towards high efficiency and greenness.

2. Comparison of standard frameworks

Standard version	Main changes	Scope of impact
GB/T 30163—2013	- Basic terms and definitions - Basic requirements for hot blast stoves	Applicable to the basic design and manufacture of blast furnace hot blast stoves
GB/T 30163—2023	- Added a flow chart for top-fired hot blast stoves - Strengthened energy-saving evaluation requirements - Added pollutant emission control indicators	Comprehensively improved the energy-saving and environmental protection performance of blast furnace hot blast stoves

3. In-depth analysis of technical requirements

Basic requirements:A blast furnace should be equipped with 3~4 top-fired hot blast stoves, and their design life should meet the use requirements of two generations of blast furnaces. The burner is arranged on the top of the furnace body and adopts a multi-hole nozzle design to ensure sufficient heat exchange between high-temperature flue gas and heat storage body.

Fuel adaptability:Blast furnace gas or mixed gas can be used as fuel, with a calorific value range of 2600~3650 kJ/m³. Pay special attention to the enrichment rate requirements of the mixed gas (1~10%) to ensure combustion efficiency and safety.

4. Implementation Suggestions

Case Analysis: Practical Application of Energy-Saving Technology of Top-Fired Hot Blast Furnace

Take a 5500 m³ blast furnace of a steel enterprise as an example, which uses 4 top-fired hot blast furnaces equipped with waste heat recovery devices and automatic combustion control systems. By implementing oxygen-enriched combustion and non-fluctuation furnace replacement technology, the thermal efficiency is significantly improved (the thermal efficiency of the body reaches 78.7%), while reducing the concentration of flue gas pollutants.

Project	Specific implementation	Expected results
Waste heat recovery device	Waste heat of flue gas is used to preheat combustion air and fuel	Improve energy utilization and reduce fuel consumption
Automatic combustion control	Real-time optimization of gas flow and air-fuel ratio	Achieve efficient and stable operation of the combustion process
